Medchemexpress LLC Biotin sulfone | 40720-05-6 | 99.8% | 276.31 | 25 MG
Biotin sulfone is a structural analog and metabolite of Biotin. It competitively inhibits Biotin in Lactobacillus arabinosus 17-5. The inhibitory potency is regulated by medium additives, with the inhibition index increasing with aspartic acid, Tween 80, and a combination of lysine, threonine, and uracil. Biotin sulfone binds tightly to streptavidin with performance comparable to that of Biotin.
